6 Sheets-Sheet 6 ,xogow estnd INVENTOR A/aaao Mae/saw ATTORNEYS PHOTOTYPESETTING APPARATUS FOR MUSICAL NOTES This invention relates to a photo-typesetting machine for musical notes, more particularly to a musical notes photo-typesetting apparatus wherein key buttons of an arbitrary number corresponding to vertical positions of musical steps, a control unit including a recording means and a pulse signal generating unit are connected to a pulse motor, which is further. connected to a magazine drum of photo-typesetting machine, such as set forth in U. S. Pat. No. 3,272,102 to Nobuo Morisawa, especially as set forth in FIGS. 6 and 12 thereof and by the operation of key buttons a certain pulse signal is generated, whereupon the pulse motor is actuated and rotates the magazine drum to the desired photo-typesetting position selected by the said key buttons from the preceding photo-typesetting position, while bringing a musical note or other musical character to the desired position of step within the fiveline and on added lines, either above or below the fiveline.

A known way of printing musical notes, using a method of plate making, requires much labor because according to this way, musical notes are first written by hand in most cases and then filmed by a plate-making camera or the like for printing. It is conceivable to apply a conventional photo-typesetting machine to printing of musical notes by replacing letters on a font slide with musical notes, rests and other musical characters. However, in order to arrange such musical characters at the desired position of step on a five-line and added lines, it is necessary to rotate each time a magazine drum either in a normal direction or in a reverse direction through the operation of a ratchet connected to the magazine drum in order to decide the position of the desired step for each musical character. Such machine operation has been impracticable because of its complexity of operation and requirement of much labor.

The primary object of the present invention is to solve the above problem in such a way as to rotate a magazine drum by a pulse motor through selective operation of key buttons in order to bring the position of the desired step to the photo-typesetting position within and without the five-line. According to this method, upon accomplishing the photo-typesetting of a series of notes of the first row, a magazine drum is moved to the second row by the operation of a handle and a graduation board, for photo-typesetting of a series of notes of the second row by means of selective operation of key buttons. Thus, photo-typesetting of musical notes can be done without interruption and beautiful musical notes can be obtained easily and mechanically on the basis of usual photo-typesetting system.

Other and further objects of the present invention will be apparent from the following description and claims made with reference to the accompanying drawings in which is shown the preferred embodiment of the photo-typesetting apparatus for musical notes according to the present invention.

Now, description is made below of one embodiment of the present invention with reference to the accompanying drawings,

Numeral 11 denotes a pulse motor; numerals 12 and 13 denote gears; numeral 14 denotes a spline shaft of a special cross section as shown in FIGS. 4 4 6, on which a driving gear 15 is mounted movably in the axial direction. Provided at the core of the driving gear 15 are rollers 17, which rotate in contact with a notch 16 of the shaft 14, making smooth the axial movement of the said driving gear 15. Numeral l8 denotes an intermediate gear; numeral 19 is a gear rotatably attached to a clutch axle 20. Numeral 21 denotes a magazine drum driving gear which has the same diameter as the gear 19 and is supported by the clutch axle 20. As

shown in FIG. 4, by fitting a key 23 in a groove 22 provided at the clutch axle 20, the magazine drum driving gear 21 rotates with the clutch axle 20. A change gear 25 is fitted around an axle 27 which is supported by an axle-supporting member 26 fixed to the side of the gear 19. By manipulating rightward or leftward a handle 28 attached to the said axle 27, the said change gear 25 is moved, together with the axle 27, in the axial direction, and by this movement the change gear 25 is made to engage with both of the gears 19 and 21 or to, engage only with the gear 21. a

When the clutch axle 20. is pushed in by a knob 29 at its end portion to the position as is shown by dotted lines in FIG. 4, a projected portion 32 provided at one end of a rotating axle 31 of a magazine drum 30 engages and connects with the groove 22 on the .clutch axle 20, whereupon a member for moving the magazine vertically and the magazine drum rotating axle 31 are connected with each other and thus a sensitive material is moved longitudinally with the rotation of the magazine drum 30.

Numerals 33 and 34 denote a magazine and a magazine table respectively. Numeral 35 denotes a sensitive material wound around the magazine. Numeral 36 denotes a bearing portion which supports the spline FIG. 1 is a sectional plan view of a magazine table shaft 14 provided at a part of the magazine table 34 and the gear 18. Numeral 37 denotes a frame supporting the magazine table 34, to which, as is shown in FIG. 1 to FIG. 3, are provided rails 38, each having a groove of V-shape cross section, which are parallel with each other at a certain distance. The magazine'table 34 is supported on the frame 37, through the medium of balls 39 arranged in said grooves and can be moved laterally, in conjunction with a lateral feeding mechanism (not shown in the drawing). Numeral 40 denotes a key board provided at a proper position of the machine according to the present invention. Numeral 41 denotes key buttons to select and decide a position of the desired step on the five-line and on the added lines of score, for example, 41a is for the first lower line and 41b is for the first lower interval 41n is for the second upper interval. Numeral 42 is a key button for photo-typesetting. Numerals 42a 42d are key buttons for photo-typesetting, of which 42a is for photo-typesetting, 42b for tooth feeding, 420 for a shutter and 42d for idle feeding.

FIG. 9 shows a plan of a font slide. The font slide consists of a lower frame 43 and an upper frame 44,

similarly to a font slide of a general photo-typesetting machine for European languages. The lower frame 43 is mounted on the frame in such a fashion that it is movable only back and forth as indicated by FIG. 9. On the other hand, the upper frame 44 is so designed that it can be moved laterally above the lower frame 43 by interposing balls 46 between each of a pair of grooves provided at the upper surface of the lower frame 43 and the bottom surface of the upper frame 44. On the upper frame 44 is provided an inserting portion 48 in which a negative plate 47 with various musical notes and characters in negative is inserted, and also provided at the front side of the upper frame 44 is an index portion 50 to insert an index board 49 with notes and characters in the same order as the said negative plate 47. Numeral 51 is a finger settling portion for operation, which is applied to bring the desired note to the.

photo-typesetting position by moving the upper frame 44 laterally or moving it back and forth, together with the lower frame 43. Numeral 52 denotes a clamping rack, which locks the movement of the upper and lower frames 43, 44 by engaging the edge of the rack locking (not shown in the drawings) with the teeth of said rack at the time of photo-typesetting. Numeral 53 denotes lateral feeding width regulating lock pins, each having a height corresponding to lateral feed width, which reguposition by way of a system shown in FIG. 11, whereupon the desired semiquaver of e on the first line is obtained. Thus, choosing of a musical interval or pitch can easily be decided by rotation of the magazine drum 30 through the operation of key buttons 41, and the length of each note can easily be decided throughchoosing the desired note among the characters on the font slide 47. In this process, the mechanism for lateral movement of the magazine drum from the point (I) to photo-typesetin the same late the lateral feeding width of the magazine according to the width of each musical character, working cooperatively with the lateral feeding mechanism. As to the said mechanism for lateral feed regulator, detailed explanation of it is omitted here as similar mechanism is shown in U. S. Pat. No. 3,272,]02 of Sept; 13, 1966. It is a matter of course that on the said font slide 47 are mounted various musical notes, rests, chord notes, treble clefs, bass clefs, sharps, flats, strength notes and any other needed characters for musical notation.

Referring to the procedure of photo-typesetting the score in FIG. 12, for example; after photo-typesetting the treble clef and the time signature, if one of the key buttons 41a which indicates the first lower line is pushed, it is linked with a control unit 54 shown in the diagram of FIG. 11, whereupon a recording device in the said control unit is actuated, which is transmitted to a pulse signal generating unit 55, which generates a certain pulse signal and transmit it to the pulse motor 11. With the rotation of the pulse motor 11, the magazine drum 30 rotates and brings the point of the first lower the point (II) can be knownfrom the mechanism as shown by U. S. Pat. No. 3,272,102 Photo-typesetting Machines. Furthermore, alteration of lateral feeding width of each note can easily be performed, using the same mechanism.

After photo-typesetting the first row according to the procedure as mentioned before, the handle 28 is manipulated to detach the change gear 25 from the gear 19 and engage only with the other gear 21 as is shown by dotted lines in FIG. 4 and then the magazine drum 30 is rotated by the said handle 28. When the magazine drum 30 reaches the point of the second row, the manipulation of the handle 28 is stopped and'the gear 25 is made to engage again with both of the gears A 19 and 21. Then, each of the notes in the second row is manner as the procedure mentioned above.

As the present invention is thus constructed, musical notes can easily be photo-typeset, using the method of photo-typesetting, especially the position (height) of each note can easily and correctly be decided by selective operation of the provided key buttons as is desired,

not only in the section of five lines, but'also in added lines to the five-line. Therefore, the present invention, in the printing field of musical notes, is really epochmaking in correctness, mechanical beauty and easiness of operation, and saving of much labor, including handwriting in the conventional photo-typesetting system. The apparatus according to the present invention is most effective for photo-typesetting musical notes, but it can be modified for application to photo-typesetting the formulas including characters other than musical characters and numerals, and also to photo-typesetting the tables and drawings.
